Basically the generator does a decent job. What I don't like is the seemingly random mix of shortages, auctions, BM options. And in the case of campaign, the offered rewards and upgrades may make strange choices.
Sometimes it fits, sometimes it is just a ragtag of different unrelated options. Unclaimed auctions are a good indicator. Sometimes (especially when you can't select a company) the map just plain sucks..
There are BM claim concessions, claim auctions, resource claim auctions, company claim auctions and building auctions. In some games there seem to be most of them at the same time... In other matches, new claims feel extremely rare.
Resources - I saw quite a few maps with almost none of one resource (carbon, silicon, even water) which makes for strange games. Especially scientists hurt a lot here. On the other hand, a scientist campaign with free patent lab, double speed and half cost achievements later on is just crazy.
If the map sets a theme, BM and auctions should support it. With huge distances, anything reducing transportation cost becomes interesting. Have severe resource limits? Directional drilling is useful, or carbon washing; BM exploration drills and Mule (although it needs a free resource). Auctions might offer new resource claims, as well as stockpiles. Attack auctions make most sense in an otherwise completely peaceful match, and so on.
This would mean to identify the map /scenario themes, and add categories to auctions and BM actions.
